After two years of research and mixed msgs from SLP, my dream is complete. My 1993 TA went from a near perfect California car with LT1 to a very nice car with the LT4 (aka, Grand Sport) engine. This task was very complex & included chip reprogramming with LT4 tables calcs for running the built 4L60, EGR delete in the ECM, 97 Dual Cat exhaust system, rebuilt 4L60 (no 4L60 E in 93) for 650 HP & 6400 RPM shifts, 2002 front & rear brake upgrade, Ram Air hood (OE) & SLP Ram Air hardware for a non-MAF FireHawk. SLP parts include the very rare Extrude-honed SS exhaust manifolds (+ 40% flow increase over LT1), SFC with tie to center mount, and special spacer for the Alt, PS, A/C bracket. It clears the valve cover & the Dual mass balancer still fits/clears below.
